To all whom it may concern Be it known that I, WILLIAM ARTHUR, a

subject of the King of England, residing at N ew Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Coasting-Registers, of which the following is a specification.

This invention relates to certain new and useful improvements in coasting registers, and pertains more particularly to a register employed for the purpose of positively registering the coasting periods, and for also enabling the power on, braking, and stopping periods to be ascertained or readily computed, to thus enable the efliciency of the conductor as well as the motorman to be ascertained.

The present invention proposes to provide. a coasting reglster which 1s active only during coasting, and which is rendered quiescent during the periods of braking power on and stopping, so that the coasting, record of the motorman alone can be accordingly determined, or by deducting the coasting record so obtained from the total time of the run, the sum of the braking, power on and stopping periods can be both easily and readily ascertained.

The motorman must complete his run-in a certain prescribed time, but if the conductor wastes time by taking too long in opening and closing the door, orv in not promptly giving the ahead signal when the passengers have been either let off or taken on, then the motorman must speed his car up in order to complete the run in the scheduled time. This deprives the motor of the opportunity of coasting and also requires a longer time of brake application, withthe result that more current is employed, and

theequipment is subjected to greater wear and tear. The increased consumption of power necessarily requires a corresponding increase in coal consumption.

The present invention therefore briefly proposes to provide a register which indicates the efficiency of the motorman alone, or of both the motorman andthe conductor, or in other words of the crew as distinguished from prio devices [which propose to indicate the efliciency of the motorman alone.

Further. and other objects. will be .laterhereinset forth andmanifested in the course of the .7 following specification.

In the drawings Figure 1 is a side elevation'of the invention; showing the same in. a case with its front removed;

Fig. 2, is a top plan view,'-the case being shown in section; v

Fig. 3, is a section on line 33 of Fig. 2;

I and Figs. 4, 5 and 6 arefragmentary' side elevations, partly in section, showing the parts during theirvarious stages of operation.

In proceeding in accordance with the invention, a suitable clock mechanism 1, is employed, the master gear 2 of which operates a pinion 3 mounted on a shaft 4:, the latter belng in suitable operative connection witha coasting register 5 which, as hereinafter explained enables the sum of the braking peried, the power on period and the stop period to be ascertained.

A pipe 6 leads from the air brake lineand has. a cylinder? connected thereto within which latter is a plunger 8 having a rod 9 connected thereto. Rod9 has a pin 10at its upper end which engages in the slot 11 of an,

arm 12, the latter mounted on a suitable shaft 13. A second arm 14 also secured to the shaft 13 and carries a light curved leaf spring brakingv and starting member 15, which latter engages aQbrake wheel 16v mounted onthe balance wheel Yarbor17 of y the clock works. i

Theplunger 9 also has an arm 18 rigidly secured thereto, the arm carrying a pin 19 at its outer end, which pinextendslthrough a j slot 20 formed in an arm 21 mounted on the hinged arm 25 carries an armature 26 which latter is attracted upon energization of the magnet, the free end of the arm being disposed so as to be capable of engaging beneath the arm 18 of the plunger rod 9 as shown in Fig. 6. A finger 27 is rigidly secured to the arm 25 and extends upwardly therefrom.

The clock is normally wound and is active during coasting, the parts in this position being indicated in Fig. 3, in which the spring brake 15 is free of engagement wlth the brake wheel 16 of the clock works, the plunger being also in its lowermost position. When the brakes are applied, air entering the cylinder 7 will move the plunger to its uppermost position as depicted in Fig. &, thereby raising arm 18, and the latter through the pin 19, slot 20 and arm 21 Wlll rotate the shalt 22 of the brake register and register a time of brake applied, on said register.

This upward movement of the plunger causes the spring 15 to move upwardly to the position of Fig. 4, engaging or braking the wheel 16 so as to cause the clock to stop.

The clock is thus caused to remain quiescent throughout the braking period. When the brakes are released the plunger drops but is caught by the finger 27, and prevented from completing its down movement, being held in the position shown in Fig. 5, so that the register will continue to remain quiescent throughout the time during which the car stops or remains at a standstill.

lVhen the motor is started the brakes being 011', and the parts in the position of Fig. 3, the magnet 2% is energized, attracting the armature 26, and moving the parts to the position of Fig. 6, in which position the spring 15 has caused the clock to still re main stopped thereby continuing stoppage of the coasting register 5, so that as long as the current remains on the register 5 will remain quiescent. This upward movement of the rod 9 is however not suflicient to operate the brake register 23 so that the latter is consequently not affected.

When the current is shut ofi and the brakes are off, with the parts in the position of Fig. 6, the arm 25 will be released, due to the deenergization of the magnet 24, and the plunger then completes its down movement, bringing the parts to the position of Fig. 3, in which the coasting register is rendered active to positively register actual coastin It will thus be apparent from the fore going that whenever the brakes are applied the brake register 23 will be operated once to indicate a time of brakes operation. As long as the brakes are kept applied the upper or coasting register 5 will remain quiescent because the lunger is kept in its uppermost position of %ig. 4, and as long as the car remains at a stop the register 5 will remain quiescent because, upon release of the brakes the plunger is prevented from completing its down movement to start the clock, due to the parts being then in the position of Fig. 5, the current being off. Then the current is on the upper register 5, will also remain quiescent throughout the length of time the current is kept on, since the plunger will be held in the position of Fig. 6, in which the clock is braked and rendered inactive. However, as soon as the current is shut off and the brakes are released, then the parts will occupy the position of Fig. 3,

in which the clock is active, and the coasting or upper register 5, is likewise rendered active to positively indicate the coasting period.

The finger 27 is preferably secured to the arm 25 so as to be readily removable therefrom, so that if desired, the apparatus will register power on and braking to the exclusion of stopping. To enable power on only to be registered, a valve 30 is placed in pipe 6, so as to allow the air to be cut oil from the cylinder, and to enable the braking period alone to be determined it is merely necessary to remove the armature carrying arm 25.
